I concur with all Ninos comments.

I started Homepin as a "hobby business" - not registered for GST and not even a registered business name. I had no idea if it would 'work' or not and didn't particularly care if it did. It was (and still is) what I like to do and there lies the most important difference.

If you start ANY business because you need or want money the chances of success are greatly diminished IMO.

If you LOVE doing what you propose then forget about the money as it will come.

Good luck with it - I am sure it would succeed.
